I wonder whether we have another way of doing this. Jonathan, Dean?
Maybe this explains why webkitpy bot is failing here.

Brendan, you can try to do what the bot is doing to reproduce the issue:
/Volumes/.. /Tools/Scripts/webkit-patch build-and-test --no-clean --no-update --test --non-interactive --build-style=release --group=webkitpy --port=mac

> Tools/Scripts/webkitpy/w3c/test_exporter.py:231
> +        return filter(lambda x: x.startswith(WEBKIT_WPT_DIR), changed_files)

Is it working for all options passed to the exporter, like if a specific commit is specified?
I also wonder whether we should do the lint once we applied the patch to the wpt repo.
That would ensure that we use the latest linter from WPT and not the one from WebKit repo.

We usually try to use self._filesystem and not os.path directly.
At some point, we might also want to have check-webkit-style do some lint, so maybe there should be a dedicated class for a WPT lint wrapper.
